[Class 83 (iv).] A solder-applying means for the side seams of cans comprises a solder bath 4, preferably divided by a number of partitions 6 perforated at 7, in each department of which runs a rotatable solder applying disc 8, 9, 10, 11 the discs operating in succession on the side seam of the can C to apply solder thereto. The arrangement is characterised in that the discs have notches or recesses 8<a>, 9<a>, 10<a>, 11<a> in their peripheral surfaces so dimensioned that in the advance of the can to positions C<1>, C<2> and C<3> solder is applied to the side seam throughout its length but, since a notch is positioned beneath the leading or following edge of the can as it is moved forward from disc to disc, no solder is scraped from the discs on to the interior surface of the can body. The discs, preferably rotatable in opposite directions, as shown, are carried by shafts admitting of longitudinal adjustment over the bath which is also adjustable vertically as well as horizontally. The driving gearing of the discs may be arranged to drive discs 9 and 11 at greater peripheral speed than 8 and 10 which move in the opposite direction to the can body. A disc 24, running in a separate solder bath, serves to distribute the solder previously applied and to reclaim surplus solder. Specification 410,186 is referred to.

The latter can be closed at one, or both, ends by means of end members welded thereto. As shown in Figs. 4-6 such an end member 20 is placed on the open end of a filled container 11 with a part 22 thereof projecting into the container and a shaped welding jaw 23 is pushed into the joint between the lid 20 and the container 11 along each side of the latter to melt the plastics at the joint and form a U-shaped recess, Fig. 5. The jaws 23 are rapidly retracted and a shaping tool 24 is lowered to form a welded joint, Fig. 6. The cover (20) can be produced by further expanding a rigid, foamed plastics, cover sheet (20) by heat from an infra-red heater (311) in a water cooled fixture (30) to raise the part (22) of the cover (20), Fig. 7, not shown.

Abstract: 1515505 Automatic steering of root crop harvesters J D DYSON and C R DYSON 4 Aug 1975 32552/75 Heading A1F [Also in Division B7] A root crop harvester has at least one pair of feelers 14 which in use takes up a position determined by the crop row being harvested, and which one misalignment of the harvester relative to the crop row is arranged to effect the steerage of the harvester in such a way that it follows the crop row. In the embodiment shown, the feelers are carried by bows 16 having two limbs 16L, 16R which are pivotally connected about horizontal axes to brackets 12 mounted on a transverse bar 10 secured to a forward part of the harvester chassis. Each limb of the bows has an upper central part 20L, 20R which carries an eye 22L, 22R; a rod 24 extends laterally of the harvester and passes through all the eyes. On each side of each eye, a spring 26 surrounds the rod and is maintained in slight compression between the adjacent eye and a collar 28 secured to the rod consequently the combined lateral displacements of all the feelers 14 result in a nett lateral force being applied to the rod 24, movement of which operates a spool valve 58 which controls the steering of the harvester.
